Study Identifies Peri-Implantitis Risk Factors



While dental implants can restore smiles, peri-implantitis remains a risk. Researchers from the Federal University of Santa Catarina and Paulista University in Brazil as well as Kristianstad University in Sweden recently identified key risk factors in developing the disease.

The study examined 183 patients treated with 916 osseointegrated titanium implants that were in function for at least one year. The implants were installed at the Foundation for Scientific and Technological Development of Dentistry at the University of Sao Paulo between 1998 and 2012.

According to the data, a history of periodontal disease increased the risk of peri-implantitis by 2.2 times. Compared to screw-retained prostheses, cemented restorations increased the risk by 3.6 times. Risk increased by 2.4 times when wear facets were displayed on the prosthetic crown. And compared to single rehabilitations, total rehabilitations increased risk by 16.1 times.

The researchers accounted for factors related to each patient’s systemic conditions, the implant’s characteristics, and clinical parameters. Logistic regression analysis did not reveal any association between the implant’s characteristics and peri-implantitis.

The study, “Risk Indicators for Peri-implantitis. A Cross-sectional Study with 916 Implants,” was published by Clinical Oral Implants Research.
